To all whom it may concern: Be it known that I, ALEXANDER Vosm'na, a subject of the gueenof the Netherlands, residing at Phila el hia, in the 'county of Philadelphia and tate" of Pennsylvania, have made certain new anduseful Improvements'in A aratus for the Production of Ozone, of w oh the following is a-specification.

Objects of the present invention are to ,provide a durable, reliable and eflicient apparatus for ozonizing air or the like; to reperforated plates or partitions orsupporting foration of the di-electric.

,vent injuryto the di-electric by reason 0 the efi'ect upon it of heat; and to obviate per- With these; objects in view I will proceed to describe an embodiment of my invention and will then claim the invention.

In the accompanying drawings, the figure is a transverse sectional view of an ozonizer embodying features of the invention.

In the drawings 1, is a tubular casing shown as cylindrical, but the word tubular is not used in this description as confined to a circular cross-section, but is intended to include any other cross-section of tubular body. At the heads of this casing there are rames 2 and 3. Extending between these parts 2 and 3, are a number of rods, bars or the like 4, the intermediate portions of which constitute electrodes ordischargers 5, which may have their surfaces serrated or may be made .u of.w1re nettmg or gauze. A

The e ectrodes 5, are of tubular form and are arran ed concentrically with and within the tubuIar di-electrics 6. The latter are supported at their ends by means of erforated or otherwise open caps 7, carrie by the rods 4, in such a way as 'to support the di-electrics and permit of some expansion and contraction thereof; for example, the lower cap 7, might be fast on. its rod while the upper cap 7, was afforded some up and down motion on the rod. Arranged around and concentric with the -di-electrics 6, are

tubular electrodes 8, which may be of gauze,

perforated metal, or the like. These elec trodes 8, are sup orted and carried by an open frame or p e orated partition 9 arrangedwithin the casing 1.

It will of course, be

understood that one set of electrodes, as'5 constitute one side of the circuit and the other set of electrodes, as 8, constitute the I fgtion ot intent Application filed owner-a2, isor Serial No; seas mrnnmsrnvm ng. A cannons-Ion hffiilrirsromm sanitation or mass.

other side of the circuit and that the parts are pro erly electric'a and through the i-electric. The di-electric is spaced'at an equal distance from each of the electrodes.

Air'or other gas to be treated passes through the casing by way of the openings- 10 and -11 formed in the ca s that are applied to the ends thereof. 11 thus passing an or other gas passes both outside and inside of the di-electrics and thro h the field of electrical action. The fact t at the diinsulated to bring about an dischar e between the electrodes electrics are free to expand and contract naturally protects them from breakage due to heat The spacing of the electrodes at equal istance from the di-electric brings about substantially the same potential diflerence on each side of the di-electric and in this way the di-electric is protected from undue strains. The tubular form of the' units which make up the electrodes insures a large surface so that there is a relatively low current density per, square unit and this also tends to'protect the di-electric from undue strain. I

As shown in the drawings an allowance is not made for the diflerence in surface between the inside and outside electrode and the di-ele'ctric is shown as spaced equally between them. This is'done because the diflt'erencein surface is considered negligent.

What I claim is 1. An ozonizer'comprising a casing provided with supports and through WlllOl'l air -or the like may pass and a Cplurality of units arranged in the casing an each consist' of a rod carried by tWo' of said supports an Erovided intermediate of its ends with a tuular discharger or electrode, a tubular dielectric arranged around and clear of and concentrically with the rod, caps for spacing and sufporting the di-electric. in respect to the ro and for permitting of the passa e of air and the like, and a second electrotIe or discharger arranged concentrically with and around the di-electric and at substantially the same distancefrom it as the first mentioned electrode and .held to place by one of said supports, substantially as described.

2. In an ozonizer the herein described group of units for an electrode each consistmg 0 a rod provided intermediate of its ends with an electrode, a tubular di-electric encirclin said rod and spaced from and ar- I for retaining said last mentioned electrodes 10 range concentrically with it, devices for in the positlons descnbed.

movably supporting the dielectricin respect air and the like thro h It and a secon tubular electrode encircllngthe di-electric and arranged concentrically with it and spaced at su stantially' the same distance from it as the first mentioned electrode, and means In testimony whereof I have hereunto to the rod and permittmg of the pass eof signed my name in the presence of two witnesses.
